when changing to hot side on an 04 is it true that when you change them the turbo isnt balanced and you should have a place do it so that it comes out balances and then it wount blow?

 

Who told you that???

 

Can't even see why this would be the case as you don't touch the wheels... I did this in my garage in a few hours...

 

I never heard anything like that. I think somone is pulling your ******.

 

someone was telling me that i shouldnt try to take it apart and put it back together it should be balanced or it would blow after a while

 

I saw someone say that on a thread here too, but that's bs.

 

has anyone had any problems?

 

besides the fact that the hotside swap is not worth it , there isn't any problems doing it clean without balancing

 

???? Where did that come from? People pay more for an intake to gain less...

 

its impossible to put in the wrong direction because there is a little pin on the compressor side and a hole for it on the hotside. align the hole with the pin and clamp. . . wala. . . done. There should be no problems whatsoever.

 

Maybe the person that told you that you would need the turbo rebalanced was confused because you probably told them that you were gonna change the hotside as opposed to just the turbine housing. I, for one , had never heard of a turbine housing refered to as a hotside, until I joined this forum. To me, at least, in the past, the term hotside incuded both turbine wheel and housing.

Maybe the fella figured that you were gonna be removing the compressor nut and separating the compressor and turbine wheels from the shaft, and then changing to a different turbine wheel. In this case, the turbo might need to be balanced.

There are 2 ways to do the balancing: Either the wheels can be balanced separately(off the shaft) or the 2 wheels, the shaft and the compressor nut can be balanced as a unit. If the rotating assembly is balanced as a unit, then it is balanced assembled incuding the nut, in which case, the nut is ground to indicate exact position upon reassembly.

 

Personal experience. I swapped and wish I hadn't People think that this switch is like a power monster. It is not. My gains were minimal at best and I am on race gas . I can see how the paper Pushers could see big things being as it is larger, but in my experience the switch from the 9.8T to the 10.5T wasn't what it is cracked up to be . This can be verified from myself and the Tuner Dan Harman.

 

One example maybe, but on most cars, it does make a difference. 15-20whp for $250 is pretty good. It's also not just the peak power gain but the boost sustainment and area under the curve.

 

Yes, Take my advice as you would the Next. Have you gone thru a swap? I thought the 05 MR came with the larger hotside? Maybe I have a weak car that does not respond well to mods , maybe the tuner is bad , I dunno. What I do know is that I held boost fine with the 9.8T like i do now. I Also know that the Area under the curve was quite similiar . None of this is to be arguementative ( if thats even a word ) but I sat there as it was being installed and watched it being tuned and was seriously disappointed. I now take the position of "If your gonna screw with the Turbo , go big"

 

Sorry dumb ? but if I were to get the 10.5 hotside would I have to be retuned?
